Re: [scikit-learn] scikit-learn twitter account
I have created the https://twitter.com/sklearn_commits twitter account. I have applied to make this account a "Twitter Developer" account to be able to use https://github.com/filearts/tweethook to register it as a webhook for the main scikit-learn github repo. Once ready, I will remove the old webhook currently registered on @scikit_learn account and would like to tweet about the transfer as drafted here: https://hackmd.io/@4rHCRgfySZSdd5eMtfUJiA/H1CSpuF2S/edit Please feel free to let me know if you have any comment / suggestion about this plan. -- Olivier ___ scikit-learn mailing list scikit-learn@python.org https://mail.python.org/mailman/listinfo/scikit-learn
Re: [scikit-learn] SVM-RFE
It does not provide access for tracing the step by step feature weights and predictive ability- The user provides the n_feature.
